Rectangle data. Can be set as a class instance
implementing the IDataManager interface, or as a hash.
When options are set to default values, the following data fields are interpreted by a geo object:

hintContent - Content of the rectangle's popup hint.

balloonContent - Content of the rectangle's balloon.

balloonContentHeader - Content of the rectangle balloon title.

balloonContentBody - Content of the main part of the rectangle's balloon.

balloonContentFooter - Content of the lower part of the rectangle's balloon.

The balloonContent field is a shortcut for the balloonContentBody field, but if they are both set simultaneously,
balloonContentBody takes priority.
You can also add your own custom fields to the rectangle data and use them, for example, in the balloon layout.

Enables synchronously adding an overlay to the map.
By default, overlays are added to the map asynchronously
to prevent the browser from hanging when adding a large number of geo objects.
However, adding asynchronously does not allow accessing the overlay immediately after adding a rectangle to the map.

This event is only available on devices that support multitouch.
Returns an implementation of the IMultiTouchEvent interface with information about touches.
Defines the touches property, which contains a list of touches.
Every touch is described by an object that contains the following fields:

clientX - X coordinate of the touch relative to the viewable area of the browser.

clientY - Y coordinate of the touch relative to the viewable area of the browser.

pageX - X coordinate of the touch relative to the beginning of the document.

pageY - Y coordinate of the touch relative to the beginning of the document.
